The vessel boasts a distinctive form, characterized by two umbrella-shaped pillars rising from the everted mouth rim, a contracted neck, and a bulging belly. Its circular bottom is supported by flaring, tapering triangular legs, while a semi-circular handle is attached to the side of the belly. The decoration is exceptionally intricate: the neck is adorned with plantain motifs, the belly features taotie patterns, and the interior bottom is cast with two characters, "Mu Ya."

As an important ritual vessel and wine container, the Jia played an integral role in social rituals and religious activities during the Shang dynasty. The inscription "Mu Ya" likely signifies a connection to an unidentified noblewoman or her clan, underscoring the vital role of Shang dynasty bronze inscriptions in documenting clan lineages and sacrificial practices. This vessel not only exemplifies the advanced craftsmanship of its time but also provides valuable insights into the cultural and religious traditions of the Shang dynasty.
